DISPLAGEMENT-VARYING MEANS.

Application filed. April 27, 1925.

'1 '0 aZZ whom it may concern:

Be it known that I, JONAS J. l-Lisnnnr,a

citizen of the United States, residing at Sanborn', in the county ofNiagara and State of New York, have invented certain new and usefulImprovements in Displacement-Varying Means; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My inventionrelates to improvements in means for varying thedisplacement of either air orwater craft, so that they may be made toascend or descend at the will of the'person or persons in command.

Further objects are to make novel pro vision to enable a boat to floaton top or the water, just even with the surface of the water,or underwater at any desired depth; to make provision whereby a boat may becaused to either sink or rise, either bow first or stern first, or toascend or descend uniformly at both its bow and stern; to proin sinkingposition.

Figure 3 is a view similar to Fig. 2, but showing the displacementvarying device in rising position.

Figure 4t is a vertical transverse sectional view as indicated by line4.-t of Fig. 2.

In the drawings above briefly described, B designates the hollow body ofa submersible ship which may well be provided with any desired form ofconning tower C, equipped preferably with self-closing hatches toprevent entrance of water when the ship submerges. At the stern and bowof the body B, I have shown devices D for varying the displacementofthe'ship either uniform- 1y or unequally at its opposite ends, so thatit may be made to ascend or descend either stern first or how first, orascend or descend Serial No. 26,201.

uniformly at both ends. The constructions of the two devices D areidentical and hence only one is shown and described in detail.

The numeral 1 designates a stationary cylinder rigidly secured to thebody 13 and open at its outer end, while its inner end 2 is closed.Telescopically engaged with this stationary cylinder 1, is a slidablecylinder 3 which may either fit within or around said stationarycylinder. The cylinder 3 is open its inner end but is closed at itsouter end, the latter being preferably conical as indicated at at. Toform fluid-tight seals between the two cylinders, two flexible sleeves 5and 6 have been shown. The sleeve 5 surrounds the outer end of thecylinder 1 and is suitably secured thereto as indicated at 7. Thissleeve also surrounds the cylinder 3 and is secured thereto at 8. Thesleeve 6 is within the two cylinders, and has its ends connected theretoin a. fluid-tight manner as indicatedat 9 and 10.

Means are provided for either projecting or retracting the cylinder 3and it will thus be seen that the displacement of the ship may bevaried, as occasion may demand. For illustrative purposes, to effectthis adjustment of the cylinder 3, I have shown internally threadedtubes 11 extending longitudinally of the cylinders and disposed at theexterior thereof, these sleeves being suitably secured to lugs 12carriedby the cylinder 3 and passing slidably through guides 13 which aresecured to the stationary cylinder 1. A number of screws 1-1 arethreaded into the sleeves and extend through appropriate stuifing boxes15' into the interior of the body B to be simultaneously driven by anypreferred means. Gears 16 have been shown on the inner ends of thesescrews.

Preferably, a bag 17 is provided in the telescopic cylinders, suitableprovision 18 being made for inflating or deflating said bag. Byinflating the bag, to a pressure approximating that of the fluid aroundthe ship (either air or water), the cylinder 3 may be more easilyadjusted and the external pressure is counteracted so that it will haveno tendency to crush the cylinders. Moreover, when the invention is usedon a submarine,

the air-filled devices D will assist materially in bringing the ship tothe surface in case of accident. A suitable pressure gauge 19 may beconnected with the bag 17 so that the latter may be inflated to anyadequate extent, without guesswork.

From the foregoing, taken in connection with the accompanying drawings,it will be seen that simple provision has been made for varying thedisplacement of a ship which is sustained by displacement of fluid(either water or air). Thus, the ascent and descentof such ship may bereadily controlled as occasion may require, it being o1 course wellknown that the bouyancy ot the ship increases proportionately withincrease of its displacement, and decreases as the displace-' ment isdecreased. 0t cou se, when the invention is used on an airsnip haying abag, provision will be made for introducing gas into the bag 1?. butwhen the invention used on a submarine, both the body B and said bagwill contain air.

\Vhile good results may he obtained from the details disclosed, it to beunde stood that they are for illustrathre purpo. only and that withinthe scope of the invention as claimed, modifications may be made.

I claim:

1. In a ship sustained by displacement of fluid; a displacement va yingdevice comprising a cylinder stationarily carried by the body of theship, said cylinder having an open outer end, a slidable cylindertelescopically engaged with the stationary cylinder and having an openinner end and a closed outer end, sealing means preventing entrance ofsurrounding fluid into the cylinders, said sealing means comprising{lexible sleeves disposed one around and one within said cylinders, theends of said sleeves being secured to the stationary and slidablecylinders respectively, and means for sliding the slidable cylinderseither outwardly or inwardly.

2. In a ship sustained by displacement of tluid; a displacement Varyingdevice comprising a cylinder stationarily carried by the lJOC y of theship, said cylinder having an open outer end, a slidable cylindertelescopically engaged with the stationary cylinder and having an openinner end and a closed outer end, sealing means preventing entrance o'tsurrounding tluid into the cylinders, an intlatable bag within saidcylinders, a closure for the inner end ot the stationary cylinder, andmeans for sliding the slidable cylinder either outwardly or inwardly.

3. In a ship sustained by displacement of fluid; a (llSlQltltQlHODtvarying device comprising a cylinder stationarily carried by the body ofthe ship, said cylinder having an open outer end, a slidable cylindertelescopically eng ed with the stationary cylinder and haying an openinner end and a closed outer end, sealing means preventing entrance ofsurrounding tiuid into the cylinders, and means for sliding the slidablecylinder either outwardly or inwardly, said sliding means comprisingradial lugs at the outer end of the stationary cylinder, internallythreaded tubes slidable through the lugs and haying their outer endstixed to the outer end portion of the slidable cylinder, and screwsmounted on the inner end of the stationary cylinder and rotatable in thetubes to effect movement of the sliding cylinder either inwardly oroutwardly.

In testimony whereof I haye hereunto aliixed my signature.
